Recommend you do two (2) things. First, go down to the local Ford dealer Parts Department and ask them if they no if the car requires a "vented" gas cap and if so, then recommend you replace it if Ford has one it will be expensive, but most likely you will need to go top a local car parts (NAPA, PepBoys, etc.) And see what they have a well, sounds like your old cap is bad & that does happen, and some cars require a 'vented' cap.
